Database replication, distributed caching, and service-to-service API calls all rely on the underlying network’s ability to handle microbursts and maintain low round-trip times. This flow is typically routed through a centralized firewall, making it a natural inspection point.
Achieving Predictable Non Blocking Connectivity for East West Traffic
The Role of Visibility and Monitoring Effective management of east west traffic requires deep visibility into internal flows. North south traffic enters the data center through an edge, traverses core and distribution layers, and reaches a final server before exiting back to the user or another external service.
Unlike north south traffic, which is easily monitored at the edge, internal communication can be opaque without the right tools. Attackers who breach the perimeter can move laterally across the internal network with relative ease, targeting vulnerable services that communicate freely.
Achieving Predictable Non Blocking Connectivity for East West Traffic
However, the dramatic rise of virtualization, containerization, and microservices has shifted the center of gravity, making east west traffic—the communication between servers and applications inside the data center—dominant. This requirement has driven the adoption of leaf spine architectures, which replace traditional three-tier models to provide predictable, non-blocking connectivity.
